What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Baltic Aquascaphe MK2

The Baltic Aquascaphe MK2 is widely praised for its refined case design, improved lume with applied markers, and added crown guards, presenting a sharper and more purposeful neo-retro dive watch. Owners and reviewers highlight its updated technical and design elements, including a fully graduated sapphire bezel and two case size options (37mm and 39.5mm), all while maintaining a reasonable price point. Some find the design derivative or less cohesive than its predecessor, with one owner noting the long, straight lugs as a significant drawback, while others appreciate the dial texture and case profile. The Baltic Aquascaphe MK2 is powered by the Miyota 9039 movement with a 42-hour power reserve and offers 200m water resistance. Overall, owners and reviewers rate the Baltic Aquascaphe MK2 highly for its value and contemporary updates to a tool-watch heritage.

From video reviewers

The Baltic Aquascaphe MK2 features 3D Super-LumiNova indexes for improved legibility. A notable weakness is the lack of lume brightness. Reviewers disagree on the optimal case size, with one reviewer noting a 41mm stainless steel case is comfortable for everyday wear, while the other mentions 37mm and 39.5mm case sizes are available.

Seiko Prospex SPEEDTIMER Seiko 145th Anniversary Limited Edition

Owners widely praise the Prospex SPEEDTIMER Seiko 145th Anniversary Limited Edition for its refined presence and intricate dial patterns, with some favoring its unique red dial and steel bezel over other Speedtimer models. However, some owners criticize the 24-hour subdial as useless, the date window as recessed, and the stock bracelet as difficult to fit, while others find the pushers stick out too much. One owner notes the $995 price point is high for the 6R55 movement, suggesting a lower range, though others appreciate the Seiko finishing and charm. On balance, owners rate the Prospex SPEEDTIMER Seiko 145th Anniversary Limited Edition well for its unique aesthetic and finishing, despite some functional and value concerns.
